Anybody have a verizon boulder? I'm thinking about getting one. here are my main concerns- battery life & call quality. I've heard people say the battery life sucks but I saw a review where a guy said he just ran it all the way down a charged it back up a few times and its got good life. any likes/dislikes? and how hard would it be for me to use a song on the phone/memory card as a ringtone? thanks
